Manipulating doublearrays – an extension method

I’ve been fiddling around with returning JSON from an Asp.net MVC solution and getting it in Jquery using the $.getJSON method. Unfortunately – when the default JSON serializer in .net serializes my doublearrays it takes the values of the first column first, then the next column, etc. I would like it to serialize it as one row, then the next, etc.

I am aware that this is default behavior and that I could just populate the doublearray with rows as columns and vice versa, but I find it more intuitive to be able to refer to the first indexer in an array as x and the second as y, like this:

byte[,] data = new byte[3,3];
int x = 2;
int y = 1;
data[x,y] = 1;

Therefore I created a little extension method for manipulating doublearrays. You may find it helpful if you need to rotate an array, or swap values vertically or horizontally.
